Due to the enormous amount of possible interactions, test engineers have to decide which test aspects to focus on. In this paper, we examine what types of failures can be found in graphical user interfaces for automotive infotainment systems and how frequently they occur. A hierarchical classification for failures has been developed based on common concepts in software engineering, such as Model-View-Controller and Screens. More than 3,000 failures, found and fixed during the development of automotive infotainment systems at Audi, Bosch and Mercedes-Benz, have been analyzed. Results show that 62% of reports describe failures related to high and low level behavior, 25% of reports describe failures related to contents and 6% of reports describe failures related to design.
